Patented Get. (5, 1931 rates mares EDWARD BOLLINGERI, OF SAN FRANCISCO, CALIFORNIA InsULAToB. son AUTOMOBILE 1100138 Application filed April 26,

This invention relates to an insulator for the hoods of automobiles and its object is to prevent the heat from the engine from spoiling the paint on the hood.

Another object of the invention. is to provide a protection which can easily be applied to automobile hoods where they are not factory equipped with such protection, or

removed therefrom at will whenever necessary.

A further object of the invention is to cause the insulation to'lie snug against the inside of the hood and to prevent any oil splash from soaking into the asbestos insulation.

Other objects of the invention will be apparent as the description proceeds.

An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout the several figures of the drawings and of which there may be modifications.

Figure 1 is a view of the inside of one portion of an automobile hood showing the insulating member attached thereto,

Figure 2 is a view partly in perspective of one of the spring straps for holding the aluminum sheet and the asbestos lining in place. i

Figure 3 is a sectional view of the automobile hood at one end thereof showing the holding straps, asbestos insulation and the aluminum lining therefor,

Figure 4 is a side elevation of one of the longitudinally extending holding straps,

Figure 5 is a plan view of one of the holding straps showing the securing lock,

Figure 6 is a plan view of one of the holding straps,

Figure 7 is a plan view of the other holding strap, and,

Figure 8 is a detailed view enlarged to show the clips for holding the aluminum sheet 3 in place.

The numeral 1 indicates the upper portion of the hood of an automobile; 2 representing a sheet of asbestos insulation thick enough to prevent injury to the paint on the hood 1 from A sheet of aluminum 3 United States is as follows, but modifications 1927. Serial 1%. 186,618.

covers the asbestos and prevents the splash of oil from soaking into the asbestos. I

V A fiat steel spring 4, of which there'may be several if desired, is used to hold the aluminum sheet and asbestos in place, while at right angles thereto there are the spring steel straps 5 and 6, each strap having a hook 9 at its ends to engage the edges of the hood, and atthe center the two straps are held together by means of a flat clip 10 which takes the ends of both straps of a pair. The steel straps 7 and 8 run parallelto the steel spring 5 and serve a similar purpose.

, The ends of the straps 5 and 6 opposite from the hooks are provided with a series of holes 11, which holes areengaged by the end of the locking lever 12 adjust the length of the straps in order to draw them tight against the hooks at the edges of the hood ends, thereby pressing the flat steel springs and the insulation tightly against the underside of the hood.

It will be apparent from the construction just outlined that this protection can be ap plied to any automobile hood readily and without in any way disfiguring or cutting holes in the hood.

The aluminum lining 3 which serves to protect the asbestos from soaking up oil and grease is provided, with a series of integral clips 14 and 15 wherever one of the holding straps passes over the edge of the aluminum sheet, said clips being formed by making two outs in the aluminum'sheet and bending the clips thus produced downwardly over the holding strap. Note particularly the detailed construction in Figure 8, and the holding. clips at the edge of the aluminum wherever one of the holding straps passes over the edge of the. aluminum sheet.

It will be understood that the same arrangement may be used for the sides of the hood or for the cowl wherever it may be desired.

Having thus described my invention, what I desire to secure by Letters Patent of the may be made in the specification and drawings within the purview of the annexed claim 1. A device of the class describedcomprising a sheet of heat insulating material, a thin metal sheet to cover said insulating sheet, 1190 spaced vertical steel straps on said metal strip, spaced horizontal steel straps on said metal sheet, clips on the edges of said metal sheet adapted to clamp said steel straps in place on said sheet, the end portions of said steel straps extending beyond the edges of said metal sheet and having hooks adapted to engage the edges of an automobile hood, said horizontal straps comprising two parts having overlapping ends, said overlapping ends having spaced holes therein, a locking lever to engage said holes to adjust the length of said horizontal straps to tighten said hooks on said hood, and a clip to slide over the end of said lever and said straps to hold the lever in a locked position.

2. An insulator for automobile hoods comprising a sheet of heat insulating material, athin metal sheet to cover said insulating sheet, spaced vertical metal straps on said metal sheet, means to hold said straps on said metal sheet, spaced pairs of horizontal straps hm'ing hooks to engage the edges of an automobile hood and each pair having overlapping cnds, means to hold said straps and said metal sheet together, said overlap ing ends having spaced holes therein, a ing lever for each pair of straps adapted to engage said holes to adjust the length of said horizontal straps, and a clip adapted to slide over the overlapping ends and over the locking lever to hold said lever in the locked posi tion.

In testimony whereof I have hereunto set my hand this 14th day of April, A. D. 1927.
